Ratio $L_3^2/L_1^2$ of the largest to the smallest eigenvalue of the radius of gyration tensor of the chain as a function of the distance of the center of mass of the chain from the center of mass of a silica nanoparticle. The systems consist of chains of molar mass $M=208$ kg/mol and one nanoparticle of radius either 3 nm (silica volume fraction ${\mathit{\varphi }}_{{\text{SiO}}_2}$ = 1%) or 6 nm (${\mathit{\varphi }}_{{\text{SiO}}_2}$= 3 and ${\mathit{\varphi }}_{{\text{SiO}}_2}$ = 6%). The expected value from the random walk model for bulk PS is also included (black dotted line) [148]. (Reproduced from Ref. [153] with permission from The Royal Society of Chemistry.)
